Description

Dispenser for rolls wound up

The present invention relates to an output device for roll-wound flat products comprising a cover part having a front wall and a housing part, the housing part comprising a rear wall and a first and second side wall, forming an inner space, and a use of the dispensing device according to the invention. Dispensing devices of the type mentioned for the output of rolls

wound flat products are widely known from the prior art. In addition to such dispensers, which store only a single roll, those are also known which store two rolls, so that when a first roll is completely used, a second roll is tracked and made available to the user of a dispenser. Such dispensers facilitate their maintenance by operators who insert reels into the dispensers, thereby reducing costs.

Such devices, which output to roll wound flat products, be it those which have a perforation or the like to form individual surface portions, be it those which form an endless roll without any perforation or the like, often have the disadvantage that the mechanism for

Tracking the second replacement role in consumption of the sheet product of a first role is complicated. Often this will be the user of a corresponding

Output device proposed those which have two parallel juxtaposed rollers flat products. But here, too, the user must manually move, for example, a housing part along a longitudinal axis of the rollers to then have access to the replacement role. In addition, problems arise due to the replacement of rolled to rolls flat products of different widths. The latter is due to production technology, so that often the tracking mechanism does not work properly or the roles are not applicable because too narrow or too wide. It is therefore an object of the present invention to provide an output device which can also take up and deliver rolled-up flat products of different widths. To solve this problem, an output device of the type mentioned is proposed, wherein a pressure arm is provided, which is mounted at its one end and cooperates with an actuating means, so that exerted in one direction from one side wall to another side wall, a pressure on an insertable role becomes. The direction of the pressure is in the sense of the present invention as effectively perpendicular to a plane that passes through the side walls to respond. By such

Embodiment of the dispensing device according to the invention advantageously an adjustment mechanism is provided, which in particular when using rollers of different widths, which already exist in terms of production, in the

Dispensing device according to the invention allows a fine adjustment of the holding pressure, so that the rollers safely, for example in guideways, which are provided in the device according to the invention, are guided.

The adjusting means according to the present invention may also be referred to as adjusting or adjusting means. It serves to make an over the pressure arm on the role, in particular finely adjustable, applied pressure adjustable. Thus, the pressure can be adjusted via the adjusting means, which acts on the pressure arm and thus also on the roller. As a result, by the operator who either waits for the device according to the invention or refills rolled-up flat products, can set the pressure with which the pressure arm exerts pressure on an insertable roller via the adjusting means. Thus, in particular production-technically unavoidable differences in the width of sheet-like products wound into rolls can be easily compensated, so that they are arranged securely removable in the device according to the invention. If, for example, a roll of a wound flat product having a greater width is used, then the pressure acting on the pressure arm is reduced via the setting means; if a roll of wound flat products with a smaller width is used, the pressure of the pressure arm is adjusted by adjusting the setting means; which on the pressure arm acts, increases accordingly. The mode of operation of the actuating means of the device according to the invention can also be described in such a way that the action path of the pressure arm is influenced, in particular adjusted, by this adjustable and in particular also finely adjustable.

The pressure arm itself is located on a side wall of a roll wound flat products in operating position, that is in the filled state of the device according to the invention, to. It rests on the lower roll, whose flat products of a

As far as in the present invention, the term "about" or "substantially" is used in terms of values or ranges of values, this is to be understood as meaning that the person skilled in the art will regard as expert in the given context.

In particular, deviations of the stated values of +/- 10%, preferably +/- 5%, from the term "about" or "essentially" are included. As far as in the context of the present invention, the speech is that one or the other means associated with one of the two side walls, so this is not to be understood that the respective means are arranged directly on the side wall. Rather, it may also be in the sense of the present invention z. B. be that the side walls in turn assigned insert parts which are aligned more or less parallel to the side walls, and therefore can be addressed as lateral inner walls. Arranged on these inserts means are also as in the context of the present

Invention associated with the side walls view. Of course, the respective means can also be assigned directly to the side walls.

As far as in the context of the present invention, the speech is that the hinge axis of the swing arm between front wall and rear wall is aligned, this is to be understood such an orientation in which the hinge axis is formed approximately at right angles with respect to the front wall and rear wall.

As far as in the context of the present invention, it is mentioned that the hinge axis is aligned transversely to a longitudinal extension of the swing arm, as the latter is an education to understand in which the swing arm extends longitudinally between a bottom part and a top floor of the dispensing device according to the invention. The dispensing device according to the invention may have a topsoil which is part of the cover part or of the housing part, and is preferably part of the cover part. The bottom part can also be formed by the cover part or by the housing part in the sense of the present invention, for example, a collecting means may have, with which empty rollers or the aforementioned inserts (plugs), at both ends of an inner core, as an inner wrap or sleeve, the roll of sheet-like products are introduced, are collected.

According to the invention, a device for exchanging a first used-up roll of planar products by replacing a second roll of flat products is made available, without the user of the output device having to take measures for this independently beyond the usual tearing off of flat products. For example via guideways, in particular those which are prepared for said plugs, and which are arranged on the first and second side wall facing the interior of the dispensing device according to the invention, a first roller inserted by an operator, it runs along surfaces of the holding part and the guide part within the guideway in a consumption position. In this case, the swing arm of a receiving position moves about its axis of rotation such that the holding part projects into the interior of the dispensing device according to the invention and a support for a

to be inserted spare role, which is held in this holding position spaced from the first consumption role.

In a particularly preferred embodiment, the holding part comprises an angled holding portion at its upper end region. As a result, it is advantageously possible that with only a small overall depth with respect to the joint movement of

Schwingarmes a sufficiently secure attitude of the replacement role in the holding position in the dispensing device according to the invention is provided.

More preferably, a surface of the holding part and a surface of the

Holding portion an angle ß in a range of about 25 ° to about 75 °, more preferably in a range of about 35 ° to about 50 °. With such an angular range, a small overall depth with respect to the articulated swing arm is achieved based on the overall size of the dispensing device according to the invention.

In another embodiment, the holding portion has first and second surfaces facing the interior of the dispenser housing. The first surface of the holding portion preferably connects to the surface of the holding member such that the first surface of the holding portion with respect to the surface of the holding member into the interior of the housing of the dispenser by an angle of about 5 ° to about 80 °, preferably about 10 ° angled to about 45 °. The second

The surface of the holding portion preferably connects to the first surface of the holding portion such that the second surface of the holding portion with respect to the first surface of the holding portion from the inside of the housing of the dispensing device to an angle of about 30 ° to about 120 °, preferably about 60 ° to about 95 °, angled.

In a preferred embodiment, the swing arm has an angle γ between a longitudinal side edge of the guide part and a lower edge of a subsequent section. Preferably, the angle γ has a value of about 85 ° to about 140 °, more preferably a value of about 105 ° to about 125 °. The section adjoining the guide part and encompassed by the latter is preferably elongated and preferably lies in a plane defined by a surface of the guide part

or is formed in the direction of the hinge axis. The section preferably has a thickness corresponding to the guide part. The section may, for example, also have the same width as the guide part below the holding part, and thus also be addressed as an angled extension of the guide part. Preferably, the arranged at the lower end portion of the guide member portion is formed as arranged in the direction of the hinge axis broadening portion. In the direction of the articulation axis in the context of the present invention means an orientation in a plane in which the articulation axis, which runs transversely to a longitudinal extent of the oscillating arm through it, and which extends between a bottom part and a top floor of the device. A joint housing, which is provided for fastening the swing arm in the housing part, which at least partially comprises the hinge axis, is preferably designed to extend in the direction of a widening section. By the widening portion has in a lateral view, as seen from the direction of the opposite side wall, the swing arm a roughly beater-like,

especially hockey or golf club style appearance.

Preferably, the widening portion has a greater width than the remaining part of the swing arm. Preferably, the broadening portion has a width at least about 10%, more preferably about 50% greater than the rest of the swing arm. in the

In connection with the oscillating arm, the width is preferably to be understood as the magnitude of a vector which is substantially perpendicular to the direction of translational movement of the vector Role in consumption of sheet products within the device and is perpendicular to the normal of the side walls of the housing part.

In a particularly preferred embodiment, the angle γ is between a

Longitudinal side edge of the guide member and a lower edge of the widening portion in a range of about 85 ° to about 140 °, more preferably in a range of about 105 ° to about 125 °. In such an embodiment of the swing arm is due to the widening portion with a reduction of the roll diameter by

Handling of the sheet product of the role by the user nonetheless provided over a maximum contact surface of the leading role a secure hold until the last flat product is unwound from the roll.

In a further preferred embodiment, the widening portion has an upper edge which is s-shaped from the guide part towards its end. Due to this s-shaped upper edge, a considerable spread of the widening section is achieved. The upper edge is preferably in the direction of in the inventive

Issued used output device rounded out, as is preferably the case with all edges of the swing arm, which are facing the role or the case. Due to this broadening due to the s-shaped course of

Upper edge of the widening portion of the guide member is provided a secure guidance of the roll, from which a flat product is unwound by a user, even at a reduced diameter thereof.

Further advantageously, the lower edge of the widening portion is substantially rectilinear. This ensures, among other things, that a

Removal opening of the output device according to the invention is not reduced in size over the fee.

The angle γ of the oscillating arm causes, in particular, a roll of flat products provided with inserts in the core ("plugs") from the upper one

Holding position in the lower dispensing position of the dispenser first in Essentially moved along the swing arm from top to bottom. Below the angle of the swing arm described by angle γ at least partially a movement of the roller along the swing arm in the direction of the front wall of the

Output device instead, to a point where the roll of sheet products to an inner surface of the front wall of the dispenser applies. By this contact of the roll of sheet products with the front wall of the dispenser, as a first advantageous effect, the roll of sheet products is securely held in position.

With decreasing diameter of the roll of sheet products by use, the roll of sheet products is guided further toward the front wall of the dispenser along the swing arm of the dispenser and initially remains in contact with the front wall of the dispenser. With further decreasing diameter of the role of flat products due to use, the role of flat products moves to the end of the swing arm. As soon as the roll, as the diameter decreases further, may lose contact with the front wall of the dispenser, this destabilizes the roll of sheet products even prior to complete consumption of the sheet product. This could lead to the fact that the role of flat products collapses before the complete consumption of the sheet product by a divergence of the plugs or staggered and the removal of the sheet product is hindered. To almost completely consume the role of sheet products, i. H. at low

Diameter of the roll of sheet products, which in particular is no longer in contact with the front wall of the dispenser, but also before to ensure a sufficient stability of the roll in the dispensing position, the end portion is below the angle γ described bending preferably as a broadening section and on preferably as a hockey or golf club-shaped widening section

intended. As a second advantageous effect, the lack of stabilization of the roll at a greatly reduced diameter after almost complete use of the roll, which may be particularly caused by the loss of contact with the front wall of the dispenser, is enhanced by the broadened contact surface of the "plug"

Broadening section offset. In a further preferred embodiment, the hinge axis, based on a total length I of the swing arm, about 30% to about 50%, preferably about 38% to about 48% of the total length I below an upper end of the swing arm arranged. The hinge axis is advantageously displaced eccentrically in the direction of the end region of the guide member. By such an arrangement it is ensured that the hinge mechanism when using a consumption role and subsequent use of a spare roll, which is held in the holding position, works safely. It is ultimately achieved that the swing arm can be made very compact, and no other aids except a bearing of the swing arm on the joint housing arranged on this example on a pin-like, preferably in cross-section part-circular projection, arranged in an insert part, which is associated with the side wall is, or untermittelbar in the side wall, is necessary, wherein a connection between the joint housing and storage means can be done for example by a latching of the joint housing on the storage means.

In a preferred embodiment, the swinging arm is arranged in a first guide track, assigned to one of the two side walls. The guideway can be arranged on an insert part, parallel to the side walls in the interior of the housing part. The arrangement within the guideway ensures the operation of the swing arm when using a consumption role and subsequently a replacement role. The guideway is advantageously designed such that in this a roll of flat products, provided with a core arranged in the insert part (plug), is performed. More preferably, the first guide track in an upper end region at an angle which corresponds approximately to the angle γ of the guide member. More preferably, a wall of the first guide track is formed such that an insert part ("plug") of the roller along the wall is feasible, so that the wall of a sliding or rolling surface to

Provides. The guide track preferably comprises a web formed on a wall part or an inner surface of a side wall. This web has the wall, which faces the swing arm. The web is preferably comprised by the swing arm formed and its outer edges adapted at least in the region of the guide part. The (inner) wall of the web is preferably spaced from a circumferential

Side edge of the swing arm forms. In the upper part of the holding part with the

Holding section, the web has an angled portion to form a widening for simplified recording of the roller-surface product.

In a preferred embodiment, the first guide track is substantially adapted to an outer contour of the swing arm. Especially in the field of

Widening portion of the swing arm is adapted to the first track of the outer contour thereof.

The first guide track advantageously has a projection in the direction of the interior of the housing part with respect to a surface of the guide part or of the holding part of the swing arm, so that reliable guidance of the consumable roller is ensured.

The first guide track preferably has a projection in a region with respect to a surface of the guide part of the swinging arm. In the context of the first guide track, "supernatant" is to be understood as meaning that the first guide track has a greater extent into the interior of the housing at least in one area than the swing arm, regardless of the position in which it is located In this way, when the consumable roll is exchanged for the replacement roll, the swing arm can move sufficiently far, with its holding section in the direction of the one side wall of the housing part

move so that the supply roll is transferred from its holding position and is transferred along the surfaces of the holding part, and the guide member, in the issue position. In a further preferred embodiment, in a region facing the widening section, the first guide track has a second recess. This serves to receive the widening portion in a swinging back of the same when using a consumption role before introducing a supply roll. As a result, the dispensing device according to the invention can ultimately be made small in size with regard to its width.

In a particularly preferred embodiment, the first guideway has a width b] which is greater than a width b _{2 of} a second guideway opposite thereto, which is assigned to the further side wall. If, in particular, the abovementioned plugs are used to hold the flat products wound up into rolls, it is possible with a corresponding configuration of the plugs to reliably avoid incorrect insertion of the roll since only that insert part for the roll (plug) can be inserted into the respective guideway. which also receives a corresponding width thereof, and is not wider than a plugs arranged on the

Guide means, which is arranged in a cylindrical shape projecting in the direction of the guide track on the replacement part.

In a further preferred embodiment, at least two positioning means with end faces, which are arranged on an inner side of the front wall of the cover part

End regions of the first and second guideway are assigned. These at least two positioning means with end faces support the unrolling of the consumable roll in the dispensing position in the region of the broadening section of the guide part, so that unwinding takes place as far as possible without jamming of the flat product wound into rolls.

In a further preferred embodiment, the side wall, which is opposite to the side wall with the swing arm, a pressure arm for adjusting a holding pressure for used in the device rolling flat products is arranged. By the pressure arm and a corresponding adjusting device, it is easily possible for an operator of the embodiment of the invention, even with different roller widths, the already conditionally conditioned to adjust a holding pressure such that nevertheless a secure guidance of the rollers used in the dispensing device according to the invention is ensured, as well as a safe removal of the respective surface portions of the sheet product from the output device.

In a particularly preferred embodiment, a collecting means is arranged below the removal opening provided in the device. The collecting medium is used in particular for receiving spent winding or roll cores for the rolls and / or the mentioned insertion parts (plugs) after complete unrolling of the flat product from a roll. The moment the reel is fully unwound, the plugs move freely and fall into it

Collecting means into it, as well as inner winding or roller or the sleeve, which can also be mounted split. In such an embodiment, each insert part (plug) is inserted in a partial role. By complete unwinding, the pressure on the

Broadened range of the guide means canceled, the swing arm swings back to a receiving position, and the spare role can be transferred to the use position. It can also be provided that, instead of or in addition to the mentioned insertion parts (plugs), it is also possible, for example, to use sheet-like products wound into rolls, which have a so-called two-part winding or shrink wrapping

Roll core or sleeve, which would also be safely caught in the collecting means, so a last sheet would be deducted from this of the consumption role.

More preferably, the present invention relates to a swing arm formed as described above. In particular, the swing arm has a holding part and a

Guide member, between which a hinge axis is formed between a front wall and a rear wall of an output device, in which the
